In recent years, smart micro-projection has been favored by users with its compact size and flexible delivery mode, especially since it has been received by young users. As a veteran projector manufacturer, Optoma has launched a mini-projector product in 2008. At that time, the product received widespread attention from the industry and was extremely popular. In February of this year, after reviewing market experience and in-depth analysis of user needs, Optoma launched its own new micro investment SL1. Today, let us experience how this new product will bring a new experience.
Optoma SL1 basic properties
Optoma SL1 uses Texas Instruments DLPTM technology, with 500 ANSI lumens, 1280 x 800 physical resolution and 3000:1 ultra-high contrast, to provide users with adequate hardware protection for daily display. At the same time, the machine also has 8-core processor, 4-core graphics processor and 1G cache / 8G memory to ensure the smooth running of the machine.
Optoma SL1 uses a simple design, metal color and white echo each other, stylish and generous. Three-dimensional only 158mm × 120mm × 31mm, the volume is very small, easy to carry.
Optoma SL1 includes rich interfaces such as USB 2.0, USB 3.0, HDMI, AV, and cable interfaces, and it includes almost all the interfaces required for everyday devices, and fully meets the diverse needs of users for daily entertainment. In addition, the Optoma is also prepared to prepare a signal line for AV analog audio and video signal cable to 3.5mm head in the accessories, which is very intimate.
Optoma SL1 human function
Optoma SL1's main function keys are ingenious with touch-sensitive design, giving users a novel control experience. In the switch and focusing knobs, traditional mechanical design is adopted, which can affect the normal operation of the machine due to daily mistakes and misoperations. It is very intimate and humanized.
Optoma SL1 uses a mesh design in the heat vent to prevent dust and debris in the daily environment from entering the projection, effectively extending the life of the machine.
Optoma SL1 has a screw hole in the middle of the bottom. The user can use it with a tripod every day and it can be used flexibly in a variety of complex environments. The concealed stand on the bottom of the machine is combined with body correction for easy desktop projection.
Optoma SL1's remote control uses a white matte shell, which is light and thin. The button is made of soft rubber with a black pattern logo. The function is clearly marked and the feel is excellent.
Optoma SL1 system interface
The Optoma SL1 system was developed based on Android 4.4, which can effectively manage built-in applications. Different from the traditional UI, the right half of the main interface of the machine is attached with prompt information related to daily life such as the date and weather. The left half clearly shows the functions of the projector, including applications, information, resource management, system settings, etc., to facilitate users to select relative functions according to actual needs.
Optoma SL1 can release memory and clean up the garbage to improve the machine performance. You can enter the setup menu by clicking the setup button on the remote control. Of course, you can also access the setup menu through the main interface, but the style of the setup menu is slightly different. The menu is more modern, while the main interface menu is biased towards the traditional projection interface style.
Optoma SL1 performance measurement Our test of the projector mainly through the brightness measurement, work heat and body weight and other angles to test, due to the different use of the environment, users should consider their own playback environment, and external light effects and other factors Our test will also minimize the error and provide you with objective data for reference only.
♦ Spectrophotometer We measure the actual brightness and contrast of the projector product through a spectrophotometer. The photometric method determines the substance by measuring the absorbance of the measured substance at a specific wavelength or within a certain wavelength range. Quantitative analysis. The commonly used wavelength ranges are: (1) an ultraviolet region of 200 to 400 nm (2) a visible region of 400 to 760 nm, and (3) an infrared region of 2.5 to 25 μm (in terms of wave number, 4000 to 400 cm).
Spectrophotometer
♦ Electronic weighing We will objectively weigh the product during the test. Weighing takes the total weight of the body and the necessary wire, making the weight reference for the user when carrying the projection device.
♦ Temperature measurement**
Using the principle of infrared temperature measurement, the radiant energy emitted by the infrared rays emitted by the object is converted into an electrical signal. The size of the infrared radiant energy corresponds to the temperature of the object itself. According to the size of the electrical signal, the temperature of the object can be determined.
♦ Test result
Edit Comment: Optoma SL1 performed well in the overall evaluation, the official 500 ANSI lumens, measured 301 ANSI lumens, edge brightness unevenness of 1.52, the actual performance is very good.
Optoma SL1 high-definition sample test We take a look at the effect of the product in practical applications in the final comparison, the most useful use of home projectors is the video playback, while the HD movie playback is also very test the product details and color performance ability. In the following tests, we all selected high-definition pictures for fixed scene shots.
Edit Comment: Optoma SL1 in the high-definition sample details of the precise description, a good transition between the front and rear view, the screen leveling better.
Optoma SL1 has no shading test In our previous test, many netizens were very concerned about the picture of the machine in the presence of ambient light. For this reason, we tested the machine without shading, and we used the same HD. The picture is taken with a fixed scene shot, so that everyone has a more intuitive understanding of the actual rendering of the picture.
Edit Comment: Optoma SL1 in the absence of shade scenes, the actual performance is very good, colorful, accurate display screen details, can fully meet the user's daily viewing requirements.
Optoma SL1 document picture and focus ability test document picture test can accurately and effectively reflect the projector's product in the details of the quality and text performance, while the product's focus ability can be detected.
Edit Comment: Optoma SL1 has excellent performance in focusing test, focusing accuracy, clear text display.
Summary Through this evaluation, we can see that the measured performance of the Optoma SL1 is not much different from the nominal value. The performance of the screen color is particularly bright and can easily meet the daily needs of users. In addition, the rich content resources enhance the user's home viewing experience. Key touch design, heat vent mesh design and bottom turnbuckles and other details of processing, so that its sense of control greatly improved while enhancing the flexibility of the machine, very human.
In fact, in most people's minds, Optoma is an established projector manufacturer with obvious advantages in the home market and engineering market. Like the recently launched 4K home projector series, outstanding color performance, excellent product performance is very eye-catching, has become the home market explosion. In the micro-projection block, everyone thinks that Optoma is a new recruit. Actually, Optoma has launched micro-projection as early as 08, and has foreshadowed it. The launch of the Optoma SL1 compact size, powerful performance, flexible applications, user-friendly details are all proclaiming the profound knowledge of Optoma.

Rack Mounted PLC Splitter
The PLC splitter is used to separate or combine optical signals. A PLC is a micro-optical component based on planar lightwave circuit technology and provides a low-غير مجاز مي باشدt light distribution solution with the small form factor and high reliability.
Rackmount Splitter is manufactured using silica glass waveguide circuits that are aligned with a v-groove fiber array chip that uses ribbon fiber. Once everything is aligned and bonded, it is then packaged inside a miniature housing. PLC splitter has high-quality performance, such as low insertion loss, low PDL, high return loss, etc.
Advantages
Suitable for multiple operating wavelengths (1260nm – 1650nm); unstinted.
Equal splitter ratios for all branches.
Compact configuration; smaller size; small occupation space.
Good stability across all ratios.
High quality; low failure rate.
